Square root equal for each term .
Now, First we will make the no. Inside square root equal for each term.
The first term is,
254
 We can write it by using factors of 54,
254=29 × 6
9 is perfect square of 3, so it will come out,
=29×6=2 × 36
=66
Second term is,
623
Now,
We will take 6 inside the root we get
=23× 36
=24
=4 ×6
4 is the perfect square of 2 so it will come out.
=26
The third term is,
=96
Now,
we can write it by using factor of 96
=16×6
16 is a perfect square, so it comes out as 4.
=46
Now the equation will be,
254-623-96
